Hrmm, I wonder what this user could possibly have to do with reaped nodes in the Newest Nodes listing . . . .

At any rate that's what I use to clean Newest Nodes. I rarely if ever hit the section pages directly so it doesn't do anything there, but it cleans NN pretty well (perhaps pm_clean_nn would be a better name). If they want to actually see the expunged nodes it's a starting point (Warning: noob jquery follows . . .).

  function pm_clean_reaped() {

    $('td.node-from-594086').each( function( idx ) {
      // tbody > tr > this td
      var containing_ele = this.parentNode.parentNode;
      if( containing_ele ) {
        var reaped_td = $( "td.reaped", $(containing_ele) )
        if( reaped_td.length == 0 ) {
          $(containing_ele).append( '<tr><td colspan="2" style="font-s
+ize: 0.7em;" class="reaped">Reaped: </td></tr>' );
        }

        var reaped_node_href = $( $('a', this ) ).attr('href');
        $( '<a href="' + reaped_node_href + '">X</a> ' ).appendTo( $("
+td.reaped", $(containing_ele) ) );
      }

      $(this.parentNode).remove();
    } );
  }

Of course one could use this as a starting point for further filtering (e.g. modify it to take the selector to filter on and a label (and class) to use in place of "Reaped"). Update: yup, just did it; so I can now let the neenery settle to the bottom of each section.
